Prescription medications

If you are taking nitrates you will not be prescribed Viagra under any circumstances

 

This is because Viagra and Nitrates have similar effects in causing the muscles to relax and the vessels to enlarge. When this occurs the blood pressure drops and, in conjunction, the two medications can cause a drastic drop in blood pressure. This can often be detrimental to the health of patients, particularly those suffering from a heart condition such as angina, as it can instigate a heart attack.

Viagra and nitrates are dangerous

Nitrates: Examples of nitrates are glyceryl trinitrate, isosorbide mononitrate and nicorandil.

Amyl nitrate: More commonly referred to as poppers, amyl nitrate will also lower your blood pressure dangerously if used in conjunction with this impotence treatment.

If you are taking alpha-blockers you should inform your doctor

 

Alpha-blockers are used to lower high blood pressure. If controlled, Viagra can be taken safely with alpha-blockers such as Alfuzosin and Indoramin. If you are taking alpha-blockers, your doctor or pharmacist will start you on a low dose of Viagra initially and monitor your reaction before raising the dosage.

Non-prescription medications

Although most herbal medications and supplements will not have any negative effects when taken with Viagra, it is important to mention them to your doctor if you take them regularly, as in conjunction with other medications or conditions they can have negative side effects.

St. John's Wort, a herbal remedy often used to treat depression, can be taken with Viagra without presenting a health risk. However, it can reduce blood levels of the medication and therefore reduce its effectiveness, as well as causing the Viagra to be eliminated from the body more rapidly than usual.

Other impotence treatments

If you are taking any other medications for the treatment of erectile dysfunction, such as Levitra or Cialis, you should not take Viagra at the same time. This is because the combination of the two drugs can lead to an excessive amount of sildenafil in the blood, causing the blood pressure to drop dangerously low.

Food and drink

Viagra and grapefruitAlthough Viagra can be taken with or without food, heavy and greasy meals can make the medication take longer before becoming effective. Eating grapefruit or drinking grapefruit juice may increase the blood levels of Viagra, so it is advisable to avoid it. Viagra will be most effective if it is not mixed with alcohol.
